Noice filter warning

Anonymous · ‎10-04-2021

I am getting

"Using feature AOV 'denoise_albedo'
    Filters for feature and light AOVs are different: denoising works better with matching filters.
Using feature AOV 'N'
    Filters for feature and light AOVs are different: denoising works better with matching filters.
Working with 5 frames at

I am also seeing this in the documentation

The beauty must use the same filter (gaussian_filter) as the other denoiser AOVs (N, Z, variance, and denoise_albedo), which are created by the Arnold plugin for you.

Is beauty not already gaussian? set in the sampling tab?

Or is there another place I need to set the filter?

Thanks

What version of Arnold?

Can you post the noice command line?

And the Arnold log for the render (at least the part that shows the list of AOVs) ?

Thanks

I have to think it is this:

00:02:08  9968MB         | [aov] registered driver: "/out/rop_ar_main:exr:aov13:renderCamera_MAIN" (driver_exr)
00:02:08  9968MB         | [aov]  * "Z" of type FLOAT filtered by "/out/rop_ar_main:closest_filter:aov13" (closest_filter)

Another thing to check is the metadata in the EXR. That's what noice is actually reading.
For example:

C:\htoa\scripts\bin>oiiotool -v --info  denoiseme.0007.exr

Trying to understand the warning, is it saying that the filter for the feature aovs has to be the same as rgba correct?
Metadata:

arnold/aovs/denoise_albedo_noice/filter: "gaussian_filter"
arnold/aovs/denoise_albedo_noice/filter_width: 2
arnold/aovs/denoise_albedo_noice/lpe: 1
arnold/aovs/denoise_albedo_noice/lpe_expression: "((C<TD>A)|(CVA)|(C<RD>A))"

arnold/aovs/RGBA/lpe: 1 
arnold/aovs/RGBA/lpe_expression: "C.*" 
arnold/aovs/RGBA/source: "RGBA"

They are the same, is it possibly reporting this regardless? looking around at other posts on here, even ones you've posted it seems like this error pops up everytime

Stephen.Blair · ‎10-06-2021

I don't see the Z metadata.

Could you post the full output of the noice command? And the full output of the oiiotool command? thanks

interesting there is no Z, I am making my own Z aov for this rop. Does noice want to make its own?

looking again, I forgot that I am writing Z out to a seperate exr

Stephen.Blair · ‎10-06-2021

Ah, separate EXRs for everything. You're right, that may always trigger the warning (eg it's a bug). I was testing with a merged EXR,

Ok cool thank you for the help! One less warning to worry about 🙂
